enable goal expansion for CLP(ℤ) goals
 2020-04-30 18:20:27 -03:00
Markus Triska
1dbadbfc35 enable goal expansion for CLP(ℤ) goals 
Example:

    integer_successor(I0, I) :- I #= I0 + 1.

Yielding:

    ?- listing(integer_successor/2).
    integer_successor(A,B) :-
       (  integer(B) ->
          (  integer(A) ->
             B=:=A+1
          ;  C is B,
             clpz:clpz_equal(C,A+1)
          )
       ;  (  integer(A) ->
             (  var(B) ->
                B is A+1
             ;  C is A+1,
                clpz:clpz_equal(B,C)
             )
          ;  clpz:clpz_equal(B,A+1)
          )
       ).

Thus, fast low-level arithmetic is used whenever possible.

a39f4b4487 correct verify_attributes/3 for variables that have no CLP(ℤ) attribute attached (#373) 
Example:

    ?- freeze(B, queen_value_truth(C,N,B)), Q #= N #<==> B.
       clpz:(Q#=N#<==>B), clpz:(B in 0..1), freeze:freeze(B,queen_value_truth(C,N,B))
    ;  false.
